BACKGROUND OF THE PRESENT INVENTION

1. Field of Invention

The present invention relates to a vehicle fuel system, and moreparticularly to an intake enhancement system, which substantially coolsthe air/fuel intake before the air/fuel enters into the internalcombustion engine so as to maximize the efficiency of the internalcombustion engine.

2. Description of Related Arts

It is a scientific fact that an internal combustion engine operates lessefficiently at warmer ambient temperatures. Accordingly, warmer airintake combined with warm fuel creates a potentially lean condition or“vapor lock” that can damage the engine. A cold air intake can cool downthe air flow before entering into the internal combustion engine inorder to increase engine power and efficiency and to improve throttleresponse and fuel economy in most cases.

A conventional cold air intake is an external device installed into thevehicle in order to incorporate with the air intake system of thevehicle for increasing the amount of oxygen available for combustionwith fuel. Since cooler air has a higher density, cooling the air intakeand fuel promotes an increased density of fuel. Denser fuel combinedwith cold intake air promotes better and more efficient burning of thefuel, so as to generate more power, greater fuel efficiency, and lessgreenhouse gas emissions.

Generally speaking, the conventional cold air intake comprises a heatshield isolating heat from the engine to the air intake pipe such thatairflow can be directly guided to the engine while being heated by theengine. However, the heat shield can only prevent the airflow beingheated up by the heat generated from the engine; it does not cool downthe airflow before the airflow enters into the engine.

Another advantage of the invention is to provide an intake enhancementsystem, wherein the combustion element is guided to flow along the heatexchanging duct of the heat exchanger of the vehicle in a spiraldirection for enhancing the heat-exchange between the combustion elementand the heat exchanging agent.

Another advantage of the invention is to provide an intake enhancementsystem, which does not require altering the original structural designof the heat exchanger of the vehicle to incorporate with the intakeenhancement system, so as to minimize the installation cost of thepresent invention to be used in the vehicle.

Another advantage of the invention is to provide an intake enhancementsystem, which does not involve complicated or expensive mechanicalcomponents to minimize the manufacturing cost of the present invention.

Accordingly, the vehicle, such as a car,motorcycle, boat, or truck, generally comprises an internal combustionengine 10 and a heat exchanger 20 for generating a cooling effect.

The heat exchanger 20, which can be an air conditioning system,comprises a compressor, a condenser, an evaporator, and a heatexchanging line operatively connecting the compressor, condenser, andevaporator for guiding a flow of heat exchanging agent, such asrefrigerant, among the compressor, condenser, and evaporator for heatexchange. In particular, a heat exchanging duct 21 is formed along theheat exchanging line to operatively link all components of the heatexchanger 20.

The heat exchanger 20 further defines a low pressure side and a highpressure side. The low pressure side of the heat exchanger 20 is definedat the portion of the heat exchanging duct 21 extending from theevaporator to the compressor, wherein the heat exchanging agent isguided to flow along the heat exchanging duct 21 at the low pressureside from the evaporator to the compressor. The high pressure side ofthe heat exchanger 20 is defined at the portion of the heat exchangingduct 21 extending from the compressor to the evaporator through thecondenser, wherein the heat exchanging agent is guided to flow along theheat exchanging duct 21 at the high pressure side from the compressor tothe evaporator through the condenser. In particular, the heat exchanger20 further defines a suction section and a discharge section as shown inFIGS. 1A and 1B.

Accordingly, for some vehicles, especially for heavy duty trucks orluxury car, the heat exchanger 20 further comprises an auxiliary heatexchanger for enhancing the cooling effect of the main heat exchanger.The intake enhancement system of the present invention is adapted toincorporate with the heat exchanger 20, including the main heatexchanger and the auxiliary heat exchanger, in order to cool down thecombustion element before entering into the combustion engine 10. Thecombustion element is airflow and/or a flow of fuel delivering to thecombustion engine 10 for combustion.

The heat exchanger 20 can also be embodied as an intercooler of thevehicle, wherein the intercooler is an air-to-air or air-to-liquid heatexchange device for internal combustion engine 10 of the vehicle toimprove the volumetric efficiency thereof.

According to the preferred embodiment, the intake enhancement systemcomprises an intake cooling unit 30 for delivering the combustionelement to the combustion engine 10, wherein the intake cooling unit 30is thermally conducted with the heat exchanger 20 for heat-exchangingwith the combustion element so as to substantially cool down thecombustion element along the intake cooling unit 30 before thecombustion element delivers to the combustion engine 10.

It is worth mentioning that the combustion element for the combustionengine 10 is a mixture of airflow and fuel. The airflow is drawn intothe combustion engine 10 along an air intake line of the vehicle. Thefuel is guided to flow from a fuel tank to the combustion engine 10along a fuel intake line of the vehicle. Accordingly, there are two waysto heat-exchange the combustion element with the heat exchanging agent.First, the flow of combustion element is detoured to the heat exchanger20 as illustrated in the first embodiment. Second, as an alternative,the flow of heat exchanging agent is detoured from the heat exchanger 20to heat-exchange with the combustion element as illustrated in thesecond embodiment.

As shown in FIG. 7, the present invention further comprises a method ofenhancing an efficiency of the internal combustion engine 10 of thevehicle, which comprises the following steps.

(A) Guide the combustion element to thermally conduct with the heatexchanging agent of the heat exchanger 20 of the vehicle.

(B) Heat-exchange the combustion element with the heat exchanging agentto cool down the combustion element before entering into the combustionengine 10.

As shown in FIGS. 1A and 1B, the intake cooling unit 30 comprises adelivering duct 31 for guiding the combustion element to the combustionengine 10, wherein the delivering duct 31 is directly contacted with theheat exchanging duct 21 to thermally conduct the combustion element withthe heat exchanging agent. In other words, the combustion element isdetoured to the AC line in order to cool down the combustion element.

Accordingly, the delivering duct 31 is detoured to the heat exchanger 20to thermally conduct with the heat exchanging duct 21 of the heatexchanger 20 before operatively extending to the combustion engine 10,such that when the combustion element passes along the delivering duct31, the combustion element is heat-exchanged with the heat exchangingagent within the heat exchanging duct 21 before entering into thecombustion engine 10.

According to the preferred embodiment, when the combustion element isguided to flow along the delivering duct 31 in the step (A) and the heatexchanging agent is guided to flow along the heat exchanging duct 21,the combustion element will heat-exchange with the heat exchanging agentthrough the thermal conduction between the delivering duct 31 and theheat exchanging duct 21. Furthermore, the flowing direction of thecombustion element is opposite to the flowing direction of the heatexchanging agent. It is worth mentioning that the delivering duct 31 isextended along the heat exchanging duct 21 at the low pressure side ofthe heat exchanger 20 for safety purpose. In other words, the combustionelement is guided to thermally conduct with the heat exchanging agent atthe low pressure side of the heat exchanger 20. In particular, thedelivering duct 31 is extended along the heat exchanging duct 21 at thesuction section of the heat exchanger 20.

In particular, the delivering duct 31 is integrated into the suctionsection of the heat exchanger 20 for delivering cold intake air and fuelto the combustion engine 10.

For enhancing the heat-exchange between the combustion element and theheat exchanging agent in the step (B), the combustion element is guidedto flow along the delivering duct 31 in a flow-directing manner tothermally conduct with the heat exchanging agent along the heatexchanging duct 21 in the step (A). Accordingly, the combustion elementis guided to preferably flow along the delivering duct 31 in a spiraldirection to thermally conduct with the heat exchanging agent along theheat exchanging duct 21.

In order to guide the combustion element to flow in a spiral direction,the delivering duct 31 is spirally extended along the heat exchangingduct 21, as shown in FIG. 2, such that the combustion element flowsalong the delivering duct 31 to heat-exchange the heat exchanging agent.In other words, the delivering duct 31 is directly extended along theheat exchanging duct 21 in a spiral configuration.

Alternatively, the delivering duct 31 comprises a tubular duct body 311for encircling the heat exchanging duct 21 therewithin and a guiding fin312 spirally extended at an inner surface of the duct body 311 forguiding the combustion element passing along the duct body 311 in aspiral direction so as to effectively heat-exchange with the heatexchanging agent by increasing the contact surface area, as shown inFIG. 3. In other words, the delivering duct 31 and the heat exchangingduct 21 form a tube-in-tube configuration.

It is appreciated that the combustion element and the heat exchangingagent are guided to flow into a baffle in vessel structure, wherein theheat exchanging agent is guided to flow at an inner vessel while thecombustion element is guided to flow at an outer vessel while bafflesthereat to guide the flow direction of the combustion element.Therefore, prolonging the flow of the combustion element within thevessel, the combustion element can be efficiently heat-exchanged withthe heat exchanging agent.

For airflow cooling configuration, the combustion element is embodied asthe airflow being cooled down by the heat exchanger 20 before theairflow enters into the combustion engine 10. In other words, thedelivering duct 31 is an air delivering duct to guide the airflow. Theexisting air intake system generally comprises an air filtering head 32for drawing ambient air into the combustion engine 10 along the airintake line. Accordingly, the delivering duct 31 is tapped to the airintake line to detour the airflow between the air filtering head 32 andthe combustion engine 10. In other words, the airflow will guide to passthrough the delivering duct 31 from the air filtering head 32 to thecombustion engine 10. In other words, the first end of the deliveringduct 31 is coupled with the air filtering head 32 for the ambient air toenter into the delivering duct 31, while the second end of thedelivering duct 31 is operatively extended to the combustion engine.Therefore, the airflow is guided to enter into the delivering duct 31through the air filtering head 32 and is then cooled down byheat-exchanging with the heat exchanging agent before the airflow entersinto the combustion engine 10, as shown in FIG. 1A.

Alternatively, the heat exchanger 20 further comprises an accumulatorfor use in a refrigeration circuit for vehicle air conditioning system,wherein the accumulator comprises a reservoir containing the heatexchanging agent, i.e. refrigerant. The heat exchanging agent passesfrom the evaporator to the accumulator to separate any remaining liquidheat exchanging agent from the gaseous heat exchanging agent, and toallow gaseous heat exchanging agent to return to the compressor.

The delivering duct 31, i.e. the air delivering duct, is detoured fromthe air intake line and is extended through the accumulator, wherein thedelivering duct 31 is returned back to the air intake line. Therefore,the airflow is guided to enter into the delivering duct 31 and is thencooled down by heat-exchanging with the heat exchanging agent within theaccumulator before the airflow enters into the combustion engine 10, asshown in FIG. 1A.

For fuel cooling configuration, the combustion element is embodied asthe flow of fuel being cooled down by the heat exchanger 20 along thefuel intake line before the fuel enters into the combustion engine 10.Accordingly, the delivering duct 31 is a fuel delivering duct to guidethe flow of fuel, wherein the delivering duct 31 is extended from thefuel tank to the combustion engine 10 through the heat exchanger 20, asshown in FIG. 1B.

Accordingly, the delivering duct 31 is tapped to the fuel intake line todetour the airflow between the fuel tank and the combustion engine 10.In other words, the fuel will guide to pass through the delivering duct31 from the fuel tank to the combustion engine 10. In other words, thefirst end of the delivering duct 31 is coupled with the fuel tank forthe fuel to enter into the delivering duct 31, while the second end ofthe delivering duct 31 is operatively extended to the combustion engine.Therefore, the fuel is guided to enter into the delivering duct 31 fromthe fuel tank and is then cooled down by heat-exchanging with the heatexchanging agent before the airflow enters into the combustion engine10, as shown in FIG. 1B.

Alternatively, the delivering duct 31, i.e. the fuel delivering duct, isdetoured from the fuel intake line and is extended through theaccumulator, wherein the delivering duct 31 is returned back to the fuelintake line. Therefore, the fuel is guided to enter into the deliveringduct 31 and is then cooled down by heat-exchanging with the heatexchanging agent within the accumulator before the fuel enters into thecombustion engine 10, as shown in FIG. 1B.

It is appreciated that two delivering ducts 31 are configured as the airdelivering duct and the fuel delivering duct respectively to guide theairflow and fuel to the combustion engine 10 through the heat exchanger20. In other words, both airflow and fuel will be cooled down before theairflow and fuel enter into the combustion engine 10. Therefore, bycooling the air intake and fuel promotes an increased density of fuel,wherein denser fuel combined with cold intake air promotes better andmore efficient burning of fuel so as to consequently generate morepower, greater fuel efficiency and less greenhouse gas emissions.

As shown in FIGS. 4A and 4B, an intake enhancement system according to asecond embodiment illustrates an alternative mode of the presentinvention, wherein the structural configuration of the intake coolingunit 30′ according to the second embodiment is the same as that of thefirst embodiment, expect the heat exchanger 20′ is tapped to detour theheat exchanging agent to cool down the combustion element. In otherwords, the heat exchanging agent is detoured from its AC (airconditioning) line to cool down the combustion element.

According to the second embodiment, in order to detour the heatexchanging agent, the intake cooling unit 30′ further comprises acooling extension duct 33′ for operatively extending from the heatexchanging duct 21′ to detour a flow of the heat exchanging agent,wherein the cooling extension duct 33′ can be spirally extended alongthe delivering duct 31′ to heat-exchange the combustion element with theheat exchanging agent.

The cooling extension duct 33′ has two ends operatively coupled with asuction section of the heat exchanging duct 21′ especially at the lowpressure side of the heat exchanger 20′. Instead of directly guiding theheat exchanging agent to flow along the heat exchanging duct 21′, theheat exchanging agent is guided to detour from the heat exchanging duct21′ to the cooling extension duct 33′ and is then guided to flow back tothe heat exchanging duct 21′.

The combustion element will heat-exchange with the heat exchanging agentthrough the thermal conduction between the delivering duct 31′ and thecooling extension duct 33′. Furthermore, the flowing direction of thecombustion element is opposite to the flowing direction of the heatexchanging agent.

Accordingly, the heat exchanging agent is guided to flow along thecooling extension duct 33′ in a spiral direction to thermally conductwith the combustion element along the delivering duct 31′. As shown inFIG. 5, the cooling extension duct 33′ is directly extended along thedelivering duct 31′ in a spiral configuration. Alternatively, thecomprises a tubular duct body 331′ for encircling the delivering duct31′ therewithin and a guiding fin 332′ spirally extended at an innersurface of the duct body 331′ for guiding the heat exchanging agentpassing along the duct body 331′ in a spiral direction so as toeffectively heat-exchange with the combustion element, as shown in FIG.6. In other words, the delivering duct 31′ and the cooling extensionduct 33′ form a tube-in-tube configuration. Alternatively, thecombustion element and the heat exchanging agent are guided to flow intoa baffle in vessel structure, wherein the heat exchanging agent isguided to flow at an inner vessel while the combustion element is guidedto flow at an outer vessel while baffles thereat to guide the flowdirection of the combustion element.

Therefore, prolonging the flow of the combustion element within thevessel, the combustion element can be efficiently heat-exchanged withthe heat exchanging agent.

For airflow cooling configuration, the combustion element is embodied asthe airflow being cooled down by the heat exchanger 20′ before theairflow enters into the combustion engine 10. In other words, thedelivering duct 31′ is an air delivering duct to guide the airflow.Accordingly, the cooling extension duct 33′ is tapped to extend to theair delivering duct, wherein when the airflow is guided to pass throughthe air delivering duct 31′ from the air filtering head 32 to thecombustion engine 10, the airflow will be cooled down by the heatexchanging agent by heat-exchanging between the air delivering duct 31′and the cooling extension duct 33′. Therefore, the airflow is guided toenter into the delivering duct 31′ from the air filtering head 32 and isthen cooled down by heat-exchanging with the heat exchanging agentbefore the airflow enters into the combustion engine 10, as shown inFIG. 4A.

Alternatively, the cooling extension duct 33′ is directly extended tothe air filtering head 32, wherein when the air enters into the airfiltering head 32, the air will be directly cooled down by the heatexchanging agent passing through the cooling extension duct 33′ beforeentering into the combustion engine 10, as shown in FIG. 4A.

For fuel cooling configuration, the combustion element is embodied asthe flow of fuel being cooled down by the heat exchanger 20′ along thefuel intake line before the fuel enters into the combustion engine 10.Accordingly, the delivering duct 31′ is a fuel delivering duct to guidethe flow of fuel, wherein the delivering duct 31′ is extended from thefuel tank to the combustion engine 10 through the heat exchanger 20′, asshown in FIG. 4B.

Accordingly, the cooling extension duct 33′ is tapped to extend to thefuel delivering duct, wherein when the fuel is guided to pass throughthe fuel delivering duct 31′ from the fuel tank to the combustion engine10, the fuel will be cooled down by the heat exchanging agent byheat-exchanging between the fuel delivering duct 31′ and the coolingextension duct 33′. Therefore, the fuel is guided to enter into the fueldelivering duct 31′ from the fuel tank and is then cooled down byheat-exchanging with the heat exchanging agent before the fuel entersinto the combustion engine 10, as shown in FIG. 4B.

It is worth mentioning that the intake cooling unit 30′ can alsoincorporated the vehicle having the turbocharge system and superchargesystem. Accordingly, for turbocharge configuration, the coolingextension duct 33′ is tapped to extend to the turbocharge system,wherein the heat exchanging agent is guided to flow to the turbochargesystem in order to cool down the air being drawn by the turbochargesystem.

For supercharge configuration, the cooling extension duct 33′ is tappedto extend to a chiller unit of the supercharge system, wherein the heatexchanging agent is guided to flow to the chiller unit of thesupercharge system. It is worth mentioning that the heat exchangingagent is detoured to flow along the cooling extension duct 33′ to coolthe liquid, such as glycol, within the chiller unit so as to furthercool down the air being cooled by the chiller. In other words, theliquid in the chiller will be further cooled to cool down the airflowefficiently.

For best configuration, both airflow and fuel will be cooled beforeentering into the combustion engine 10 as shown in FIG. 8. Accordingly,the cooling extension duct 33′ is directly extended to the air filteringhead 32 to directly cool down the airflow drawn at the air filteringhead 32. In the meantime, the delivering duct 31 is tapped to the fuelintake line to detour the fuel between the fuel tank and the combustionengine 10.

Therefore, the fuel is guided to pass through the delivering duct 31from the fuel tank to the combustion engine 10 to heat-exchange with theheat exchanging agent within the heat exchanging duct 21. The fuel isthen cooled down before the fuel enters into the combustion engine 10.

Therefore, both airflow and fuel will be cooled before entering into thecombustion engine 10. It is worth mentioning that a safety valve, suchas a low pressure valve, can be incorporated with the intake coolingunit 30, 30′ for modulating the pressure, wherein the safety valve isautomatically shut off in responsive to the pressure, in order toprevent the combustion element being cooled below its freezing point.

It is worth mentioning that the intake cooling unit 30 can also firstlycool down the fuel before entering into the combustion engine 10, whilethe cold fuel can then be detoured to cool the airflow before enteringinto the combustion engine 10. In other words, the fuel and airflow willbe subsequently cooled by the intake cooling unit 30. It is appreciatedthat the intake cooling unit 30 will cool the airflow first and the coldairflow will then cool the fuel in order to subsequently cool theairflow and the fuel before entering into the combustion engine 10.
